Which step should richard perform last? Will choose brainliest. Any absurd answers will be reported.

A

Step-by-step explanation:

Our equation is: 9² + 2[(5 + 2)² - 4]. We need to use PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.

The first thing to do is to add the 5 and 2 in the parentheses:

9² + 2[(5 + 2)² - 4]

9² + 2[(7)² - 4]

Then square the 7:

9² + 2[(7)² - 4]

9² + 2[49 - 4]

Do the subtraction operation within the parentheses/brackets:

9² + 2[49 - 4]

9² + 2[45]

Square 9:

9² + 2[45]

81 + 2[45]

Multiply 2 by 45:

81 + 2[45]

81 + 90

Thus, the answer is A.

A

Step-by-step explanation:

9² + 2[(5+2)² - 4]

81 + 2[(7)² - 4]

81 + 2[49 - 4]

81 + 2(45)

81 + 90

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
